Nigeria’s electricity grid began restoration within minutes after a partial collapse on Tuesday, with authorities saying power has since been fully restored nationwide.
The Nigerian government has announced that restoration of the national grid commenced hours after its collapse on Tuesday, marking the second such incident since Friday last week. The Nigeria Independent System Operator (NISO) said in an update that nationwide electricity restoration began around 11:00 a.m. following the grid disturbance, which occurred at about 10:48 a.m. the same day.
According to NISO, the disturbance originated from the Gombe Transmission Substation and quickly spread across the network, affecting key facilities including Jebba, Kainji, and Ayede Transmission Substations. The incident led to the tripping of some transmission lines and generating units, resulting in what NISO described as a partial system collapse rather than a total shutdown of the national grid.
“The national grid experienced a voltage disturbance which originated from the Gombe Transmission Substation.
“The disturbance rapidly propagated across the network, affecting Jebba, Kainji, and subsequently Ayede Transmission Substations. The event was accompanied by the tripping of some transmission lines and generating units, resulting in a partial system collapse.
“Appropriate corrective actions were immediately implemented to stabilise the system and restore normal operations. Restoration, which began at about 11:11 a.m., has since been completed.
“The incident only affected part of the grid; therefore, it was not a total collapse as reported.”
